Abstract (en)
[origin: WO2010068336A1] This invention pertains to silsesquioxane resins useful in antireflective coatings wherein the silsesquioxane resin is comprised of the units (Ph(CH2)rSiO(3-x)/2(OR')x)m (HSiO(3-x)/2(OR')x)n (MeSiO(3-x)/2(OR')x)o (RSiO(3-x)/2(OR')x)p (R1SiO(3-x)/2(OR' )x)q where Ph is a phenyl group, Me is a methyl group; R1 is hydrogen atom or a hydrocarbon group having from 1 to 4 carbon atoms; R is selected from a carboxylic acid group or a carboxylic acid forming group or mixtures thereof; and R is selected from substituted phenyl groups, ester groups, polyether groups; mercapto groups, sulfur-containing organic functional groups, hydroxyl producing group, aryl sulphonic ester groups, and reactive or curable organic functional groups; and r has a value of 0, 1, 2, 3, or 4; x has a value of 0, 1 or 2; wherein in the resin m has a value of 0 to 0.90; n has a value of 0.05 to 0.99; o has a value of 0 to 0.95; p has a value of 0.01 to 0.5; q has a value of 0 to 0.5; and m + n + o + p + q ~ 1.
